ABSTRACT:
A signal converting apparatus includes an intra-field interpolation divice for subjecting a MUSE television signal to an intra-field interpolation, and an inter-frame interpolation device for subjecting the MUSE television signal to an inter-frame interpolation. A mixer mixes an output signal from the intra-field interpolation device and an output signal from the inter-frame interpolation device. An output signal from the mixer is converted into a corresponding signal of a predetermined scan format.
